PowerColor PCS+ HD 4870 1GB GDDR5

Article Index:   

At first glance, the PowerColor PCS+ HD 4870 1GB GDDR5 looks completely different than AMD's reference Radeon HD 4870.  While the two cards do share essentially the same PCB, their specifications and coolers are quite different.


   


The PowerColor PCS+ HD 4870 1GB GDDR5 features a custom cooler with a large, center mounted fan. To the front and back of the fan are a couple of densely packed arrays of aluminum heatsink fins, linked by four heat-pipes to a copper base that sits directly atop the GPU.  Two heat-pipes run along the top of the card and through the rear-mounted heatsink fins, and the other two along the bottom of the card and through the front-mounted heatsink fins.  The design is relatively simple and elegant, and far lighter than AMD's reference cooler.

During testing, we actually found the cooler to perform better than PowerColor's claims.  Whereas our reference Radeon HD 4870 idled at around 75'C and peaked at about 90'C, PowerColor's offering with the PCS+ cooler idled at roughly 60'C and never broke 80'C under load.  And keep in mind, this PowerColor card is factory overclocked.  The cooler definitely works well.  The PowerColor PCS+ cooler does have a drawback though--it's louder than AMD's reference cooler under light to moderate loads.  While idling, the PowerColor  PCS+ HD 4870 1GB GDDR5 is clearly more audible than AMD's reference cards, but not annoyingly so.  But under a heavy load, both cards create a similar amount of noise.


   


The actual specifications for the PowerColor PCS+ HD 4870 1GB GDDR5 consist of an 800MHz GPU clock and a Memory Clock 925MHz (3.7Gbps effective).  As we have already mentioned, there is 1GB of frame buffer memory on-board, double that of the initial batch of reference Radeon HD 4870 cards.  The outputs are identical to reference cards, however, and consist of a pair of dual-link DVI outputs and an S-Video / HD TV output.  HDMI output with audio is also available through the use of an included dongle.

I would be the first to say that, I have supported AMD/ATI from the beginning when they did the merged. all i said is let them get their act together and look they have come out with performances based video cards. I'm very happy so happy that my new system will have two.

 wardlord you should know that every company has their challenges. and when they got bought by amd they had to brainstorm how they could help one another grow. is what we call in marketing developing stage for any business.

And they are doing it very very well...

hi GFX experts, I was just wondering whether it is possible to crossfire one 512MB 4870 and one 1GB 4870?

I have the 512MB 4870 at the moment and I plan to crossfire it with another card in the future. With the enticing 1GB 4870 out now, I am not really sure how to make the right decision.

What will be performance be like? If i mix two cards with different amounts of ram (if it is possible).

Please advise. Thanks in advance.

It will only use 512mb of memory if you use the 1gb card with the 512mb card for a total of 1gb.
